“…Moderate FHR variability is a reliable indicator of fetal wellbeing in the absence of fetal metabolic academia [1] . The reliability of baseline variability (kappa statistic 0.68) in our analysis program was greater than that observed in previous studies (kappa statistics, 0.15 to 0.38) [18] , [21] – [23] . Excellent agreement of our analysis program was also found in the number of accelerations (ICC 0.85), and the validity of this parameter was similar to the study by Di Lieto et al (ICC 0.87) and better than the results of other previous reports [18] , [22] – [25] .…”

ObjectiveTo compare a novel computerized analysis program with visual cardiotocography (CTG) interpretation results.MethodsSixty-two intrapartum CTG tracings with 20- to 30-minute sections were independently interpreted using a novel computerized analysis program, as well as the visual interpretations of eight obstetricians, to evaluate the baseline fetal heart rate (FHR), baseline FHR variability, number of accelerations, number/type of decelerations, uterine contraction (UC) frequency, and the National Institute of Child Health and Human Development (NICHD) 3-Tier FHR classification system.ResultsThere was no significant difference in interobserver variation after adding the components of computerized analysis to results from the obstetricians' visual interpretations, with excellent agreement for the baseline FHR (ICC 0.91), the number of accelerations (ICC 0.85), UC frequency (ICC 0.97), and NICHD category I (kappa statistic 0.91); good agreement for baseline variability (kappa statistic 0.68), the numbers of early decelerations (ICC 0.78) and late decelerations (ICC 0.67), category II (kappa statistic 0.78), and overall categories (kappa statistic 0.80); and moderate agreement for the number of variable decelerations (ICC 0.60), and category III (kappa statistic 0.50).ConclusionsThis computerized analysis program is not inferior to visual interpretation, may improve interobserver variations, and could play a vital role in prenatal telemedicine.

“…cCTG monitoring consists in the electric recording of fetal heart rate (FHR) and can be considered the most widespread noninvasive method to evaluate fetal well-being during prenatal and intrapartum process. cCTG offered a standardized method to evaluate conventional CTG parameters and introduced quantitative measures of linear and nonlinear indices related to FHR generation as a multiparametric analysis of fetal cardiovascular and nervous activity [ 29 ]. The presence of significant beat-to-beat variation suggests intact sympathetic/parasympathetic tone and central control indicating normal central nervous system (CNS) responsiveness and normal local CNS metabolic environment reflecting fetal health [ 30 , 31 ].…”

Aim of the Study. Analyzing velocimetric (umbilical artery, UA; ductus venosus, DV; middle cerebral artery, MCA) and computerized cardiotocographic (cCTG) (fetal heart rate, FHR; short term variability, STV; approximate entropy, ApEn) parameters in intrauterine growth restriction, IUGR, in order to detect early signs of fetal compromise. Population Study. 375 pregnant women assisted from the 28th week of amenorrhea to delivery and monitored through cCTG and Doppler ultrasound investigation. The patients were divided into three groups according to the age of gestation at the time of delivery, before the 34th week, from 34th to 37th week, and after the 37th week. Data were analyzed in relation to the days before delivery and according to the physiology or pathology of velocimetry. Statistical analysis was performed through the t-test, chi-square test, and Pearson correlation test ( < 0.05). Our results evidenced an earlier alteration of UA, DV, and MCA. The analysis between cCTG and velocimetric parameters (the last distinguished into physiological and pathological values) suggests a possible relation between cCTG alterations and Doppler ones. The present study emphasizes the need for an antenatal testing in IUGR fetuses using multiple surveillance modalities to enhance prediction of neonatal outcome.

“…High inter- and intraobserver variability of obstetricians is assumed to be the main cause [9,10,11,12], hence guidelines for interpreting FHR traces have been established and computer-generated evaluation systems have been introduced [13,14,15,16,17]. …”

Objective/Aims: To investigate the presence of signal ambiguity of intrapartum fetal heart rate (FHR) monitoring during delivery by comparing simultaneous cardiotocogram (CTG), abdominal fetal electrocardiogram (ECG) with continuous maternal ECG. Methods: A total of 144 simultaneous CTG (Corometrics^© 250 series), abdominal fetal ECG (Monica -AN24™) and maternal ECG (Monica AN24™) recordings were evaluated. Main Outcome Measures: When the FHR is within 5 bpm of the maternal heart rate (MHR) acquired from the ECG, it is classified as ‘MHR/FHR ambiguity'. Statistical analyses were performed with Fisher's exact test and the Wilcoxon signed-rank test. Results: Comparison of abdominal fetal ECG against CTG demonstrates significantly less ‘MHR/FHR ambiguity' in both the first stage (mean 0.70 vs. 1.22%, p < 0.001) and second stage of labour (mean 3.30 vs. 6.20%, p < 0.001). Conclusion: Intrapartum FHR monitoring in daily practice via the CTG modality provides significantly more ‘MHR/FHR ambiguity' than abdominal fetal ECG, which also provides additional information on the MHR.
